Foresters face new and evolving challenges as society reconsiders the balance of its interests between wood production and the provision of ecosystem services in the management of forests. Whatever paths this process may take, sound and broad-based decisions will continue to require accurate and relevant measurements of current forest conditions...
El sector industrial maderero forma una cadena productiva, resumida en tres procesos: Aserrío, Secado y Remanufactura. Satisfacer el volumen demandado y cumplir con las fechas de entrega de los pedidos es importante tanto, para la cadena de producción, como para el cliente. La no integración de estos procesos, genera problemas...
Within the last 15 years, wastewater treatment plants have increasingly begun to find radioactive isotopes incorporated in biosolids. Regulations concerning the disposal of radioactive material via sanitary sewer systems were in place since the early 1960's and recently were further restricted. However, the updated regulations would not have prevented certain...
A fish sampling program was initiated at Cottage Grove Reservoir
in June of 1974 to investigate mercury accumulation in the fish.
Samples were collected periodicallv from June to November, 1974, and
from June, 1975 through January, 1976 from both the reservoir and its
tributaries. Species collected included spring chinook salmon...
From September, 1984 through March, 1985, I worked as a Visiting
Intern for the Division of Special Programs, College of Arts and Sciences,
Northeastern University (NU). My position entailed the administration and
promotion of university marine related projects. The Division of Special
Programs is responsible for the development, implementation and...
Observations of the scale-dependent turbulent fluxes, variances, and the bulk transfer parameterization for sensible heat above, within, and beneath a tall closed Douglas-fir canopy in very weak winds are examined. The daytime sub-canopy vertical velocity spectra exhibit a double-peak structure with peaks at timescales of 0.8 s and 51.2 s....
Habitat and landscape features that influence the rate of interpatch movement and colonization may determine the likelihood that a species will persist in fragmented landscapes. We simulated patch extinction by removing Carolina Chickadees (Poecile carolinensis) from woodland fragments in an Ohio agricultural landscape in January 2002. We then monitored the...
Previously published physical and biological data document a zonally oriented frontal region within the California Current system separating colder and more eutrophic water north of ≈33°N from warmer; more stratified, and oligotrophic water farther to the south. Satellite images of phytoplankton pigment from the coastal zone color scanner from 1979-1983...
A 5-year time series of coastal zone color scanner imagery (1980-1983, 1986) is used to examine
changes in the large-scale pattern of chlorophyll pigment concentration coincident with the spring
transition in winds and currents along the west coast of North America. The data show strong
interannual variability in the timing...
